Orbital replacement units (or on-orbit replaceable unit [1]: 21 ) (ORUs) are key elements of the International Space Station that can be readily replaced when the unit either passes its design life or fails. ORUs are parts of the main systems and subsystems of the external elements of the ISS, none are intended to be installed inside the ...
An orbital replacement unit or orbital replaceable unit is a modular component of spacecraft that can be replaced upon failure either by robot or by extravehicular activity. The Hubble Space Telescope (HST) was designed with 70 such parts, [ 1 ] including scientific instruments and limited-life items such as batteries.
ESP-3 was detached from its Keel Yoke Assembly (which remained in the Orbiter) and installed on the P3 Truss at UCCAS-1 on August 14, 2007 during the Space Shuttle STS-118 mission. It has seven attachment sites for ISS spare parts and assemblies, called Orbital Replacement Units (ORUs). The platform also has handrails and attachment points for ...
The first is the Payload/Orbital Replacement Unit Accommodations (POA). This is a device that looks and functions much like the Latching End Effectors of Canadarm2. It can be used to park, power and command any payload with a grapple fixture, while keeping Canadarm2 free to do something else.
The electrical connections are compatible with the Space Station Remote Manipulator System (also known as Canadarm2). It is used on the International Space Station (ISS). PDGFs can be "grappled" by the Canadarm2 robotic arm, in order to allow the arm to manipulate and power a grappled object, or be commanded by operators based inside the ISS ...
The Boeing Small Launch Vehicle is an air-launched three-stage-to-orbit launch vehicle concept aimed to launch small payloads of 45 kg (100 lb) into low Earth orbit. The program is proposed to drive down launch costs for U.S. military small satellites to as low as US$300,000 per launch ($7,000/kg) and, if the development program was funded, as ...
Nanoracks CubeSat Deployer. The Nanoracks CubeSat Deployer (NRCSD) is a device to deploy CubeSats into orbit from the International Space Station (ISS).. In 2014, two CubeSat deployers were on board the International Space Station (ISS): the Japanese Experiment Module (JEM) Small Satellite Orbital Deployer (J-SSOD) and the Nanoracks CubeSat Deployer (NRCSD).
